FASTENER.

lriginal application filed January 16, 1926, SeriaINo. 81,870.

This invention aims to provide an improved fastener casing. l

The application is a division of my prlor application, Serial No. 81,870, liled January 16th, 1926. i

In the drawings, which illustrate two preferred embodiments of my invention Figure 1 is a front elevation of the first preferred form of easing;

Fig. 2 is a side elevation of thecasmg shown in Fig. 1; i

Fig. 3 is a rear elevation of the casing shown in Fig. 1;

Fig. at is a cross section showing the manner in which the casing shown in Fig. 1 is secured to a support;

Fig. 5 is a front elevation of the second preferred form of casing;

Fig. 6 is a side elevation of the second preferred form of casing;

Fig. 7 is a rear elevation of the casing shown in Fig. 6; and

Fig. 8 is a cross section showing the manner in which the second preferred form of casing is secured to its support.

Referring to the drawings and to that form of my invention illustrated in Figs. 1 through l, I have shown a flush type casing comprising a fastener socket formed from a single piece of metal and fastening means lorrned integral with the casing for securmg it to a support.

The casing illustrated includes a generally cylindrical body portion 1 having a reduced portion 2 toward its inner end, a flange 3 at the outer end of the casing, a front face 4 generally dished toward a. stiul-receiving aperture 5 and a rounded stud-engaging wall 6 surrounding the stud-receiving aperture. The casing also presents, at its inner end, a plurality of attaching prongs 7 formed integral with the casing. These prongs, illustrated in Figs. 2 and 3, extend from the edge of the reduced portion 2 and are initially bent outwardly from the casing so that the outer ends thereof are substantially in line with the face of the largest portion of the body portion 1. The prongs are prefer ably tapered to a point and are \vedgeshaped thereby providing sharp pointed thin ends easily bendable.

The socket may be secured to the body 8 of an automobile, or other like support, by first drilling a hole in the body 8 of the car, pretterably in the wooden frame part, to provide curved outwardly when forced into the wooden part oil the body 8, thereby hooking themselves into the body 8 to secure the socket thereto so that the ordinary outward strains exerted thereon, when a stud is locked in the socket, will not pull the prongs 7 lfrec from the wooden support. Any strain exerted upon the casing would be so remote from the prongs and so unevenly exerted thereiuiion that the prongs would hold last. i

The form of attachment herein described and illustrated by the drawings (Figs. 1 through 4) may be equally useful in scur ing any casing part of a. separable fastener to a wooden support, and is not necessarily limited to use in connection with the socket part of a separable fastener. The only portion of the socket which extends beyond the side of the body 8 is, therefore, the flange 3, which, being of greater diameter than the body portion 1. oil the socket, covers the edge of the socluitrccciring recess and pro-- sents a neat and finished ai' peaiance.

lcierring to the second form of casing illustrated in li igs. 5 through 8, l havh shown a tlastenor socket similar, in coustruw tion, to the one shown and described in the lirst lt'orn'i of? socket. This casing is provided with a. series of run-utturcss; 1.0 (Fig. (l) spaced about the body portion 1. lo provide a plurality of attaching elements ll therebetween. lVhen securing this socket to the support 8, I first place the easing into the aperture therein until the inner end thereof seats againstthe wooden body portion 8 at the bottom 01? the recess. The flange 3 is spaced slightly away from the lroiit face oi. the body 8, but when pressure is applied thereto it is forced against the front face of the body, as illustrated in Fig. 8. During the illJOVG-Il'lfllltiOILGd operation, the metal of the casing between the apertures 1-4) is distorted outwardly to form th attach- Divided and this application. filed March 11, Serial No. 93,905.

loo

ing elements 11. The casing collapses be tween the apertures 10, and the attaching elements 11 are forced into the wall of the recess to hold the socket casing in place,

as shown in Fig. 8.

While I have shown and described two I preferred embodiments of my invention, it

embedded into the material of a support to secure said casing in place.

2. A flush type socket casing installation comprising, in combination, a wooden support having a recess therein, a one-piece casing presenting a. plurality of weakened portions located in the body portion of said casing, and a flange at the outer end of said casing forlimiting the movement of said i easing into said recess, said weakened portions adapted to be pressed into said support after said casim is seated at the bot- 7 tom of said recess and before said flange engages said support, thereby to secure said casing to said support.

3. A fastener casing element for appli cation to a rigid support, said casing having a plurality of circumferentially weakened portions formed in the body portion of said casing, said weakened portions adapted to be pressed outwardly to become embedded into the material of a support by pressing one end of said casing toward the other end thereby to secure said casing to the support, and a preformed flange at one end for limiting the movementof one end of said casing toward the other.

at. A flush type fastener casing having at one end means for receiving a cooperating fastener element and having a tubular portion presenting at the other end of the casing a laterally rigid portion and, between the ends of the casings, a plurality of laterally weakened portions adapted to be pressed laterally outwardly from said casing by axial movement of one end portion of said casing toward the other end portion.

In testimony thereof, 1 have signed my name to this specification.
